Maintenance of rubber rollers: The key in offset printing technology is the control of water and ink balance, and ink balance relies on the key components of rubber rollers and ink rollers, whose quality can directly affect product quality. This is especially true for gravure, embossed, and flexographic printing. Generally, printing companies need to maintain their equipment once a week, including the maintenance of rubber rollers. There are several methods of maintenance:
After completing the daily production operation, the rubber roller should be carefully cleaned and washed twice repeatedly;
2. The cleaning of printing rollers must use designated chemical agents, such as industrial alcohol, and corrosive solvents cannot be used;
3. Remove the rubber roller during holidays to prevent deformation under pressure;
4. For the protection of the surface of the printing roller, it should be wrapped in news paper and placed in a ventilated and dark place.
Rubber rollers should not be stored near large motors or generators. Because the large amount of ozone generated by these devices can cause the rubber roller surface to age and crack.
